Abstract: When the degree of crystalline orientation of polycrystalline silicon is evaluated by an X-ray diffraction method, each obtained disc-like sample 20 is disposed in a position where Bragg reflection from a Miller index face <hkl> is detected and in-plane rotated at a rotational angle ? with the center of the disc-like sample 20 as the center of rotation, so that an X-ray-radiated region defined by a slit ?-scans over the principal surface of the disc-like sample 20, to determine a chart representing the dependence of the intensity of Bragg reflection from the Miller index face <hkl> on the rotational angle (?) of the disc-like sample 20, a baseline is determined from the chart, and the diffraction intensity value of the baseline is used as an estimative index of the degree of crystalline orientation.

Abstract: A motor drive apparatus of an electric forklift includes first and second torque command value generation units that individually generate a torque command value indicating torque of a corresponding traveling motor in response to a gap between a speed command value and a speed detection value; and first and second slip detectors that individually generate a slip ratio estimation value showing a slip state of a corresponding drive wheel based on the speed detection value and the torque command value. The slip detectors individually have a first arithmetic unit which generates an inertial force estimation value proportional to a differential value of the speed detection value of the corresponding traveling motor and a second arithmetic unit which generates the slip ratio estimation value in response to a relationship between the corresponding inertial force estimation value and the torque command value of the corresponding traveling motor.

Abstract: The length of the polycrystalline silicon rod (100) is measured with a tape measure, then the polycrystalline silicon rod (100) is hit with a hammer (120), and this hammering sound is recorded in a recorder (140) through a microphone (130). Then, an acoustic signal of the hammering sound is subjected to a fast Fourier transform and a frequency distribution is displayed. Furthermore, a peak frequency f is detected which shows the largest sound volume in the frequency distribution obtained after the fast Fourier transform. The relationship between the length (L) of the polycrystalline silicon rod and the peak frequency f is obtained, and the firmness of the polycrystalline silicon rod is determined on the basis of whether or not the peak frequency f is in a range of f?1,471/L (region A).

Abstract: When a plate-like sample 20 extracted from a polycrystalline rod is evaluated, peaks can appear in a ?-scanning chart. The smaller the number of such peaks, and the narrower the half-value width of the peak, the more suitable the polycrystalline silicon rod is as a raw material for producing single-crystal silicon. It is preferable that the number of peaks in the ?-scanning chart is, for both the Miller index planes <111> and <220>, equal to or smaller than 24/cm2 when converted into unit per area of the plate-like sample. It is also preferable that the value obtained by multiplying the peak half-value width by ?L=21/2?R0/360, where R0 is the radius of the sample, is defined as an inhomogeneous crystal grain size, and that a polycrystalline silicon rod of which all the inhomogeneous crystal grain sizes are smaller than 0.5 mm is selected as a raw material for producing single-crystal silicon.

Abstract: Plate-like samples each having as a principal plane thereof a cross section perpendicular to the long axis direction of a polycrystalline silicon rod grown by the deposition using a chemical vapor deposition method are sampled; an X-ray diffraction measurement is performed omnidirectionally in the plane of each of the plate-like samples thus sampled; and when none of the plate-like samples has any X-ray diffraction peak with a diffraction intensity deviating from the average value ±2×standard deviation (?±2?) found for any one of the Miller indices <111>, <220>, <311> and <400>, the polycrystalline silicon rod is selected as the raw material for use in the production of single-crystalline silicon. The use of such a polycrystalline silicon raw material suppresses the local occurrence of the portions remaining unmelted, and can contribute to the stable production of single-crystalline silicon.

Abstract: The present invention provides a clean and high-purity polycrystalline silicon mass having a small content of chromium, iron, nickel, copper, and cobalt in total, which are heavy metal impurities that reduce the quality of single-crystal silicon. In the vicinity of an electrode side end of a polycrystalline silicon rod obtained by the Siemens method, the total of the chromium, iron, nickel, copper, and cobalt concentrations is high. Accordingly, before a crushing step of a polycrystalline silicon rod 100, a removing step of removing at least 70 mm of a polycrystalline silicon portion from the electrode side end of the polycrystalline silicon rod 100 extracted to the outside of a reactor is provided. Thereby, the polycrystalline silicon portion in which the total of the chromium, iron, nickel, copper, and cobalt concentrations in a bulk is not less than 150 ppta can be removed.

The loop process includes arranging IMEs (Interaction Mediating Elements) that move with a displacement of the structure, on a boundary of the structure, defining, within the IME, correcting functions of a pressure and a velocity of the fluid that interact with the pressure and the velocity of the fluid and the displacement of the structure, and executing a simulation based on the correcting functions, in a state in which the meshes of the fluid are mismatched to the meshes of the structure.

Abstract: When an outer circumference of a clamping portion 25 and an outer circumference of a circular outer circumference 26 are restrained by a die 6 while inserting a non-circular punch 5 into a circular hole 28, paddings 27, 27 are pressed by a semi-circular inner circumference of the die 6 to thereby be forced into interior of the circular hole 28. The volume of the paddings 27, 27 is set to be substantially the same as a volume obtained by subtracting the volume of a non-circular hole 23 in an extension shaft 2 from the volume of the circular hole 28. The circular hole 28 is deformed, and the paddings 27, 27 forced into the circular hole 28 abut with inclined planes 52, 52 of the punch 5, whereby the non-circular hole 23 is formed in the extension shaft 2.

Abstract: A process quantity measurement method with which an engine output is accurately measured in a relatively simple manner. Torque of an engine is measured based on the amount of torsion of the output shaft of the engine, and an engine output is obtained based on the measured torque. On the other hand, an engine output is calculated based on input and output heat quantity, and a difference between the engine output based on the torque and the engine output based on the input and output heat quantity is obtained in advance. When the engine is operated, the previously obtained difference is added to the engine output that is based on the calculated input and output heat quantity to obtain the engine output.
